OXI Opera: how to generate XML from XSLT with a special tag "<?Label&quo

[kaddul]

Hi!!!

i'm using a XSLT but i cannot generate the second tag <?LABEL...
that tag is special because is needed for PMS-Opera (management system for hotels).

my scenario is XML to XML

origin XML
<?xml version="1.0"?>
<Client>
<Item>
<ClientID>0000105989</ClientID>
<KeyUser>TDIAZ</KeyUser>
<Date>2011-06-23</Date>
<SystemUser>users</SystemUser>
<LastDate>2011-08-03</LastDate>
<Name>Liberty Travel</Name>
<Item>
</Client>

RESULT

bad XML for OPERA
<?xml version="1.0"?>
<Profile>
<profileID>0000105989</profileID>
<creatorCode>TDIAZ</creatorCode>
<createdDate>2011-06-23</createdDate>
<lastUpdaterCode>users</lastUpdaterCode>
<lastUpdated>2011-08-03</lastUpdated>
<genericName>Liberty Travel</genericName>
</Profile>

good XML for OPERA
<?xml version="1.0"?>
<?Label HOTEL|PROFILE|000000000000000323|SUCCESS?>
<Profile>
<profileID>0000105989</profileID>
<creatorCode>TDIAZ</creatorCode>
<createdDate>2011-06-23</createdDate>
<lastUpdaterCode>users</lastUpdaterCode>
<lastUpdated>2011-08-03</lastUpdated>
<genericName>Liberty Travel</genericName>
</Profile>


How can i put that tag <?Label HOTEL|PROFILE|000000000000000323|SUCCESS> in my result XML?
